Duplex Home Designs

Your block can work harder for you with a duplex. Live in one side, rent the other, or set up two investment properties on the same land. We specialise in creating custom duplex floor plans tailored for properties in Sydney, whether you have a compact block or a more spacious site.

Our architects design duplex house plans specifically suited to your land, rather than relying on generic templates that might not fit well. You can expect layouts that are practical, with plenty of natural light in both units, and a clear separation between the two sides.

No Compromise on Either Unit

The challenge with duplexes is fitting two proper homes on one block without either side feeling compromised. We design duplex floor plans where both units get adequate space, natural light, and functional layouts—not one good side and one awkward leftover.

Our architect considers orientation so that both homes benefit from northern light where possible. Living areas don’t overlook each other’s private spaces. Bedrooms aren’t stacked against shared walls where noise transfers. Outdoor areas are proportioned fairly. Whether you’re living in one and renting the other, or investing in both, tenants and buyers expect quality.

Two Distinct Homes, Not One Divided

When you build two homes close together, privacy can’t be an afterthought. At Dhursan Construction, we implement high-performance acoustic separation in shared walls, using insulation and construction techniques that actively reduce noise transfer. Window placement is carefully planned to avoid direct sightlines into neighbouring living areas and bedrooms. 

Outdoor areas are laid out to preserve seclusion, so neither occupant overlooks the other’s private yard. We also create independence through separate entries, driveways, and utilities, reinforcing a clear sense of ownership. With extensive experience in duplex projects, we identify and resolve privacy challenges during design, long before they become costly or impossible to fix.

Choose Your Level of Refinement

We offer a selection of signature, premium, and smart inclusions for finishes, so you can choose quality levels that match your budget and style. Our partnerships with reputable brands in the industry ensure that you’re selecting from reliable, proven products—like cabinetry, tiles, fixtures, and fittings that deliver lasting quality and refined aesthetics.

Beyond our curated inclusion packages, we provide thoughtful add-on options for those seeking to elevate specific spaces—perhaps a butler’s kitchen with premium stone, a proper home theatre system, or walk-in closet designs of your choice. These finishing touches separate a well-built house from a home you’ll genuinely be proud to live in.

Home Design FAQs

We design all types of duplexes for Sydney blocks – side-by-side layouts, front-and-back configurations, and single- and double-storey designs. Our in-house architect creates custom duplex floor plans based on your block size, slope, and council requirements. Whether you want matching sides or different layouts for each unit, we’ll design what works for your property.

We start with a free consultation to review your block and understand what you want – investment income, live on one side, or both units for rental. Our architect checks council requirements and creates duplex house plans that fit your land. You review the designs, tell us what to change, and we refine them until you’re happy, then submit them for approval.

Yes. We don’t use standard templates. You tell us what each side needs – how many bedrooms, open plan or separate living, garage requirements – and we design around that. Most people keep both sides similar for cost efficiency, but we can use different layouts if that works better for you.

The best house design depends on your block, budget, and lifestyle. Sloping blocks might need split-level designs. Growing families often need a double-storey home to maximise space. We look at orientation for natural light, council requirements, and how the layout flows for daily living. A good design works practically.

The best duplex designs maximise your block without making either side feel cramped. Good duplex house plans provide privacy between units, natural light in living areas, and functional layouts. We look at orientation, street access, and how to fit two quality homes on your land while meeting council setback and size requirements.

Yes. We prepare all documentation and submit the Development Application to the council. Our team knows what Sydney councils require for duplex designs and how to prepare plans that get approved. We manage the whole approval process, so you don’t have to deal with the paperwork.

Design and council approval usually takes 10-14 weeks. Construction typically takes 10-14 months, depending on the size and complexity. We keep you updated through the whole process with regular communication from our site supervisor.
